PROFESSIONAL EXPERIENCE

Dr. Krause has 22 years of experience in industrial hygiene, environmental science and public health, with particular emphasis in the areas of occupational health, industrial hygiene, toxicology, indoor air quality, potable water quality, and litigation support. Prior to joining FACS, Dr. Krause was the State Toxicologist for the Florida Department of Health (DOH).

Experience Related to Water Contaminants

Legionnaires disease investigations (2000 to 2016) – Investigated and consulted on numerous assessments of Legionnaires’ Disease (LD) sources. Investigations have included single sporadic community acquired cases, single occupational cases, healthcare acquired cases, and outbreaks. Performed source assessments of building water systems, hot tubs, ships, industrial processes, cooling towers, and decorative water fountains. Provided ongoing consultation for building owners during remediation efforts, long term monitoring, and oversight of construction projects that raised risks of exposure to Legionella. Worked along with water service providers and public health officials to manage occupant exposure risks. In eight of the cases I was retained as a testifying expert witness.

Lead in Water at a Child Development Center (2011 to 2012) – Provided primary consultation and technical expertise on the measurement of lead in drinking water and compliance with US EPA guidelines for testing child care facilities. I worked in conjunction with the builder, plumber, the US Army Corps of Engineers, and the US Air Force Environmental Health Section to determine the cause of elevated lead in water. Elevated levels of lead in the new construction, despite using brass fixtures that met US Safe Drinking Water Standards confounded all parties. By implementing a focused testing strategy, we were able to determine which plumbing component was the major contributor to elevated lead levels in the water. Procedures and criteria were put into place to avoid this problem in future construction.

Arsenic in Residential Well Water (2009) – While serving as the State Toxicologist for the Florida Department of Health I consulted on several incidences where elevated levels of Arsenic were detected in the water of residential drinking water wells. Because background levels of Arsenic are relatively high in Florida’s geology, drinking water can sometimes reflect the local geology. However sometimes it was the result of past industrial or agricultural practices that lead to the contamination of ground water and drinking water. Frequently, the issue was that changing health guidelines had triggered the “exceedance” of arsenic limits. In 2006 the maximum contaminant level (MCL) was lowered from 50 parts per billion (ppb) to 10 ppb as a public health measure to reduce the risk of lung and bladder cancer. This administrative tightening of standards resulted in many wells that had previously been in considered “safe” to suddenly exceed public health limits.

Pesticides in Residential Well Water (2011) – The long standing need for pesticides in Florida has resulted in the use of numerous persistent pesticides for the past 100+ years in Florida. Because many pesticides were required by the Florida Department of Agriculture the state has a robust program to test and mitigate private drinking water wells. When routine monitoring of residential wells revealed the presence of banned pesticides the State Toxicologist would be requested to perform a risk assessment. In several communities we had to evaluate the risk from consuming water that contained dieldrin, a pesticide used in agriculture and termite treatments up until the 1980’s. As part of our involvement DOH toxicologists would frequently be asked to evaluate the effectiveness of water treatment systems.

Trihalomethanes generated by residential well water treatment systems (2010) – During the evaluation of a cancer cluster in a large south Florida community the Florida Department of Health assessed the results of drinking water wells for carcinogens. The only carcinogenic substances found were Trihalomethanes. While not linked to the cancers being investigated, these findings did highlight the need for homeowners to understand and rigorously maintain and operate their drinking water treatment systems. Over chlorination combined with elevated levels of organic debris lead to the generation of low levels of Trihalomethanes. Guidance was communicated to the community in public meetings and educational materials on how to avoid this situation.

Industrial Hygiene Experience

Evaluated worker exposure and indoor contamination of an aircraft maintenance and repair operation for hexavalent chromium. Delineated the extent of contamination and prepared a remediation specification. Oversaw the successful remediation and performed post-remediation clearance testing.

Evaluated multiple chemical and biological contaminants in a 100-year-old university science center, to include organochlorine pesticides, PCBs, metals, mold, bacteria, and allergens. Evaluated air flow dynamics complicated by chemistry flow hoods and general building exhaust. Documented contaminant dust loading in occupied areas of the building that included DDT and other banned pesticides, PCBs, lead and arsenic from old taxidermy mounts. Evaluated airborne exposures of persistent chemical contaminants and communicated results to professional and academic staff throughout the project in writing and at open meetings.

Evaluated the content and emissions of mercury from resilient gymnasium flooring in Central Florida. Prepared a remediation specification and consulted on the successful abatement and disposal of the flooring.

Consulted on a US Air Force Environmental Child Development Center to determine the cause of elevated lead levels in a newly constructed facility. Developed procedures and criteria to avoid this problem in future construction and comply with the US EPA Lead and Copper Rule.

Provided consultation and technical expertise on the measurement of lead in drinking water and US Environmental Protection Agency (USEPA) guidelines for testing child care facilities.

Modeled indoor air concentrations of lead from burning a lead-containing candle and resulting child blood lead levels using the IEUBK model.

As State Toxicologist for the Florida Department of Health, reviewed and approved health consultations on lead and other soil contaminants in a Miami City Park.

Evaluated community exposure to hydrogen sulfide from a sewage lift station in Key Biscayne.

Performed sulfuric acid testing in an office building after a large battery leak event. Followed up with post-cleaning testing to ensure that residual levels in dust would not cause employee illness or equipment damage.

Lead the State of Florida’s investigation of corrosive emissions from Chinese wallboard. Evaluated the health risk of hydrogen sulfide and other reduced sulfur compounds, to residential occupants and remediation workers. Worked with Federal, State and local authorities to estimate the extent of impacted homes and to recommend interim and long term mitigation strategies.
